A 6-year-old boy had previously undergone total anomalous pulmonary venous connection repair and postoperative pulmonary vein stenosis release. Magnetic resonance imaging revealed blood stasis caused by a collision between the inflow from the pulmonary veins and the outflow from the left atrial appendage. A surgical specimen revealed evidence of advanced thrombus attachment. Infra-cardiac total anomalous pulmonary venous connection with an antler appearance may be a risk factor for thrombus formation in the left atrial appendage and for postoperative pulmonary venous stenosis due to blood flow collision in the left atrium after total anomalous pulmonary venous connection repair.
一名 6 岁男孩曾行完全性肺静脉异位连接矫治术及术后肺静脉狭窄松解术。磁共振成像显示，肺静脉流入与左心耳流出之间碰撞导致血液淤滞。手术标本显示有晚期血栓附着的证据。心下型完全性肺静脉异位连接呈鹿角样外观，可能是左心耳内血栓形成及完全性肺静脉异位连接矫治术后因左心房血流碰撞导致术后肺静脉狭窄的危险因素。
